Field of the Invention The present invention relates to a tire warning detecting device, and more particularly to a detecting and warning device for detecting the presence or absence of cracks in a tire body of a tire. [Prior Art] The full-scale development of the female-deficient vehicle's tire pressure monitoring system has been implemented after the current regulations have been standardized since 2007. The tread pattern monitoring should be the norm that will be promoted after the implementation of the tire pressure, the non-traveling tread pattern. Test Method The tire industry has 10 specifications to do, but the tread or tire wear warning in the industry has not yet found an appropriate solution. The laws and regulations around the world have been strengthened for the reduction of accidents of motor vehicles and the safety of pedestrians. The mechanisms for preventing and reducing damages in various automobile accidents require the increase of the regulations in the automobile. The development of automobile safety systems is toward integrated safety systems. The (integrated safety system) trend is moving forward. Various mechanisms for providing real-time dynamic driving status monitoring have also been added to the safety regulations required for steam locomotives in recent years. The Tire Pressure Monitoring System (TPMS) has been listed by the developed countries as a necessary monitoring device for automobiles after 2007. This business opportunity and market are highly valued by Taiwanese electronics industry who are interested in entering the automotive electronics R&D field. . The dynamic monitoring of tires and road surfaces is an important issue for the improvement of vehicle safety and energy saving functions. The instant tire pressure monitoring system provides the warning function that the tire tire pressure is lower than the set safety tire pressure, but the tire safety needs to be kept outside the safe pressure range, and whether the tire tread is in the usable state is another warning. The function. 0 0963-A21793TWF(N2); P27950014TW;chentf 5 i 200824931 In the past, the instant tread detection system was used for heavy-duty vehicles with heavy-duty weights, using piezoelectric devices (piezoelectric fibers, piezoelectric resistors, piezoelectric resistors) or piezoelectric devices and strain gauges. The combination of the strain gauges acts as a deformation sensor on the tire wall to detect information about the deformation or tilt of the tire. U.S. Patent No. 7,000,462 discloses the application of a pressure sensor to a tire, a piezoelectric device (strain gauge, piezoelectric fiber, piezoelectric crystal, piezoelectric resistor) or a piezoelectric device. The tire wall is used to achieve the tire pressure and deformation detection mechanism of the wireless communication mode, and the device for analyzing the sensing signal is disposed on the receiving host end of the vehicle. The analysis device is divided into a signal filter, a memory and a micro processing. Device. U.S. Patent No. 6,910,372 discloses a non-contact tire condition monitoring mechanism which forms a chamber for placing a monitoring device between the tire hub and the tire for filling a liquid monitoring device for liquid protection, the center of the monitoring device Part of the sensing process and the location of the antenna, the center 10 extends outward to include at least six equally spaced sensing hands, and the central portion is presented in a circular shape and is waterproofly protected. U.S. Patent No. 5,749,984 discloses a mechanism for the immediate monitoring of tire deflection by measuring the ratio of the length of the tire contact patch area to the circumference of the entire tire to detect the deflection of the tire wall. Using the sensor placed in the tire, the tire firstly sets the detection reference point for safe driving with the contact surface of the female full line, and the sensor is placed inside the tire, and the tire is safely detected during driving. Within the point, the first electronic message 0963-A21793TWF(N2) »P27950014TW;chentf 6 200824931 is generated. On the contrary, if the tire is outside the detection reference point of safe driving, the second electronic signal is generated. The device still uses a piezoelectric device, and its electronic package for charging and receiving the sensing signal is placed outside the tire frame. The digital circuit is used to calculate the number of tire rotations, and the ratio of the first electronic signal to the second electronic signal is calculated. The protection range also includes the display mechanism of the vehicle computing speed and the number of tire rotations.
